Lives for gear

It could be second order reflections (involving 2 surfaces) caused by the wall/ceiling and wall/floor edges to the left and right of the speaker positions.

One idea is to make the speaker triangle wider. If this doesn't improve the null, then I would advise installing absorption in those room edges. They would need to be similar in size to the chunks you already have in the front wall/wall edges. You may be able to borrow the top portion of those chunks and set them on the floor where the floor and wall meet.
